Hexbin Chart Node

The Hexbin Chart Node visualizes data density using hexagonal bins, making it ideal for exploring spatial or scatterplot data.

Overview​

This node requires the user to select two numeric columns (X and Y axes). The chart aggregates data points into hexagonal bins, where the color intensity represents the density of points within each bin.

Key Features​

  • Density visualization: Highlight areas with high or low data concentration.
  • Customizable bin size: Adjust the granularity of the hexagonal bins.
  • Color scaling: Supports various color schemes for density representation.
  • Dashboard ready: Integrates with dashboards for interactive exploration.

Required Data​

  • xColumn: The numeric column for the X axis.
  • yColumn: The numeric column for the Y axis.
  • binSize: Controls the size of hexagonal bins.
  • colorScale: Defines the color scheme for density representation.

How it works​

  1. Add the Hexbin Chart Node to your workflow.
  2. Connect your dataset.
  3. Select the numeric columns for X and Y axes.
  4. Configure bin size and color scale options.
  5. The node renders a hexbin chart.

Use Cases​

  • Geospatial analysis: Visualize population density or event occurrences.
  • Scatterplot aggregation: Summarize dense scatterplot data.
  • Heatmap alternative: Explore data density without requiring a grid.

Benefits​

  • Efficient density visualization for large datasets.
  • Customizable granularity to suit different analysis needs.
  • Interactive exploration with dashboard integration.
